🔧 Highlander - Rear Brake Pads & Rotor Replacement

Replacing the rear brake pads and rotors restores safe stopping power and prevents grinding, vibration, and uneven braking. You’ll remove the rear wheels, swap the rotors, install new pads (with hardware), and then confirm the pedal and parking brake feel normal.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• 🛑 Support the Highlander with jack stands—never rely on a floor jack alone.
• 🛑 Chock the front wheels with wheel chocks so it cannot roll.
• 🛑 Do not press the brake pedal with a caliper removed (it can push the piston out).
• 🛑 Brake dust is harmful—use brake cleaner, not compressed air.
• 🛑 Keep the parking brake released during rear brake work (the rear pads interact with the parking brake system).
• 🔋 Battery disconnect is not required for this repair.

📋 Before You Begin

• Park on level ground, shift to P, and release the parking brake.
• Place wheel chocks at the front wheels.
• Loosen the rear wheel lug nuts 1/2 turn using a 21mm socket and breaker bar before lifting.
• Open the hood and locate the brake fluid reservoir; keep the cap sitting loosely on top so pressure can vent while you compress pistons.
• Tip: If the reservoir is very full, remove a little fluid.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the rear

• Lift the rear at the proper jack point using a floor jack (rated 3-ton minimum).
• Set the vehicle onto jack stands (rated 3-ton minimum) at solid support points.
• Remove both rear wheels using a 21mm socket and ratchet.

Step 2: Remove the rear caliper (keep it supported)

• Turn the steering wheel is not needed for the rear; just position yourself for access.
• Remove the two caliper slide pin bolts using a 14mm socket and ratchet.
• Lift the caliper off the bracket and hang it from the suspension spring using a bungee cord.
• A bungee cord is an elastic strap used to hold the caliper so the brake hose is not stretched.

Step 3: Remove the old pads and hardware

• Pull the brake pads out of the bracket by hand or carefully with a flathead screwdriver.
• Remove the pad clips/hardware from the bracket using a flathead screwdriver.
• Clean the bracket pad-contact areas with brake cleaner spray and a wire brush.

Step 4: Remove the caliper bracket

• Remove the two caliper bracket bolts using a 17mm socket and breaker bar.
• Set the bracket aside.
• When reinstalling later: Torque to 88 Nm (65 ft-lbs).

Step 5: Remove the old rotor

• Pull the rotor straight off the hub by hand.
• If it’s stuck from rust, tap the rotor hat firmly with a rubber mallet to break it free.
• Clean the hub face with a wire brush and wipe with shop towels.
• Apply a very thin film of anti-seize compound to the hub face to help prevent the rotor from sticking in the future.

Step 6: Install the new rotor

• Spray both sides of the new rotor with brake cleaner spray and wipe with shop towels (new rotors often ship with protective oil).
• Install the rotor onto the hub.
• Hold it in place by threading on 1-2 lug nuts by hand (no need to tighten) using the 21mm socket.

Step 7: Reinstall the caliper bracket with new hardware clips

• Install the new pad clips from the rear brake pad hardware kit onto the bracket.
• Reinstall the bracket and start the bolts by hand, then tighten with a 17mm socket and ratchet.
• Torque to 88 Nm (65 ft-lbs) using a torque wrench.

Step 8: Compress the caliper piston

• Remove the old inner pad and place it against the piston face.
• Compress the piston slowly using a C-clamp (6-inch) or disc brake piston compression tool (specialty) until it’s fully seated.
• A piston compression tool pushes the caliper piston back so thicker new pads will fit.
• Watch the brake fluid level while compressing; wipe any spills immediately with shop towels.

Step 9: Install the new pads

• Apply a thin layer of brake caliper grease (silicone brake lubricant) to the pad “ears” where they slide in the clips.
• Install the new inner and outer pads into the bracket by hand.
• Tip: Do not get grease on pad friction material.

Step 10: Reinstall the caliper

• Set the caliper over the new pads.
• Install and tighten the slide pin bolts using a 14mm socket and ratchet.
• Torque to 34 Nm (25 ft-lbs) using a torque wrench.

Step 11: Reinstall wheels and torque lug nuts

• Reinstall the wheels and snug the lug nuts using a 21mm socket and ratchet.
• Lower the Highlander off the jack stands using the floor jack.
• Torque the lug nuts in a star pattern using a torque wrench: Torque to 140 Nm (103 ft-lbs).

Step 12: Repeat on the other rear side

• Repeat Steps 2 through 11 for the other rear wheel.
• Replace rear pads and rotors as a pair (left and right) for even braking.

✅ After Repair

• 🦶 Pump the brake pedal 10-15 times until it feels firm (this seats the pistons against the new pads).
• Check the brake fluid level and top off with DOT 3 brake fluid if needed.
• With the engine running, confirm the pedal stays firm and the vehicle does not creep when braking.
• Test the parking brake holding power on a gentle slope.
• Bed-in the brakes: make 6-10 moderate stops from ~35 mph to ~5 mph, with cool-down driving between stops.
• Tip: Avoid hard stops for 200 miles.
